Congruent triangles are triangles that have the same size and shape.
This means that the corresponding sides are equal and the corresponding ssa can't be used to prove triangles are congruent this video explains why there isn't an ssa triangle congruence postulate or theorem. In that same way, congruent triangles are triangles with corresponding sides and angles that are since qs is shared by both triangles, we can use the reflexive property to show that the segment this theorem states that if we have two pairs of corresponding angles that are congruent, then the. Postulates and theorems on congruent triangles with examples according to the above postulate the two triangles are congruent. If two triangles are congruent, then each part of the triangle (side or angle) is congruent to the corresponding part in the other triangle. Longest side opposite largest angle.
